Description

Dl-Lactic Acid CAS NO 598-82-3 is a versatile organic acid and a key intermediate in numerous biochemical and industrial processes. Its racemic mixture of D- and L-isomers offers unique properties for applications where optical purity is not a critical factor, providing a cost-effective solution. This product is essential for manufacturers in the food, pharmaceutical, chemical synthesis, and personal care industries seeking a reliable and high-quality acidulant, pH adjuster, or chemical building block.

Application

• Food & Beverage Industry: Used as an acidulant, pH regulator, and flavor enhancer in various products, including dressings, beverages, and confectionery.
• Pharmaceutical Synthesis: Serves as a crucial intermediate and chiral building block in the production of active pharmaceutical ingredients (APIs) and fine chemicals.
• Biodegradable Polymers (PLA): A primary raw material for the synthesis of polylactic acid (PLA), a sustainable, compostable bioplastic used in packaging and textiles.
• Personal Care & Cosmetics: Functions as a pH adjuster, humectant, and exfoliant (in derivative forms) in skin care, hair care, and cosmetic formulations.
• Chemical Industry: Employed as a solvent, catalyst, or intermediate in organic synthesis, esterification reactions, and metal processing.
• Animal Feed & Agriculture: Acts as a feed preservative and acidifier to improve gut health and inhibit microbial growth in silage and feed.
• Cleaning Products: Utilized in eco-friendly descaling agents and cleaning solutions due to its chelating and mild acidic properties.
• Leather & Textile Processing: Applied in deliming and pickling processes within the leather tanning industry and as a mordant in textile dyeing.
